- K llhis invention relates to improvements in ll springV shackle boltsand `more :particularly to yltheniea'ns rfoi-lubricating the bolts. n

.Altllughtheinvention is. illustrated and described as applied to ashackle bolt such q asemployed where the spring ofv a vehicle.Zj'oinsg-fthe frame-orchassis ,of the vehicle, it 'ivnv'vill/be,readily understood that theinventive idea :can L'beA`utilized Y elsewhere 4without ldei0 parting fr'onitlie :spirit of theinvention.

Shackle bolts in ow'known .and in use whichA are of a construction to belubricated, j: i i, hayeione ,particular weakness'or' objectionfintheiroperation'. z-It has been found thatthe 15oilor grease conduit orpassageway in the shackle'd becomes stopped up orjcloggehand e preventsanormal :oreiicient lubricationof the shackleA which yis of coursehighlyobjec- 'tiembla-71,. y 0 1; Ihe"present' invention is.l designedand constructed to V'overcome `thisV disadvantage of the present knownshaeklebQltS, and :is what we. have te'rnied a non-clogged spring Asl'iacklefbolt. v

Although wey havegdescribed and illustrated the use of bushings- 8 and13, it'will be readily understood that these canv be larged head 14 atone end while their oppositeendsare threa'dedas at; 15 to receivesuitable washers ,16` .and `nuts 17.

shackle bolt hole l18 so that lubricant can `be supplied. for passage tothe `elongated sagewaybeconies clogged, it is necessary to V entirelykremove the shackle bolt to clean it. If a wire orother like instrumentis run into the passageway, it will eventually niake l.

the situation worsefor the reason that the matter which is clogged up,Awill be pushed into the Velongated groover and eventually preventanylubrication'taking-place Y 2V. l

'To' overcome this disadvantage vve haveV provided a suitable lubricantsupplying de-V vice or fitting 20. This device can take any desirableform7 but in the drawings we have illustrated what is commonly-known asale- Vmite Vfitting which isadapted to cooperate with a greasekgu'n 'to'receive grease'nu'nderl pressure. 'i This ittingis threaded-as atf21 andthe outer end of thefdrilledhole in the shackle bolt internally-t-hreaded aszat 22 to l receive'the `fitting. .The fitting additionallyedrinto the outer-end of.l the shacklegbolt is provided at its innerendwith a *conveyf ingtube 23 which `ris of' a size lto fitthe drilled holeof' the shacklebolt.v ThisftubeA "23 is rigidly attached to'raxdfcarriedby 'the fitting 20, so that, when the fitting is thread'-y V tube, itwin Y extend throughthe hole, inthe- Abolt and end at a gated groove19.' v.
